Application filed April 4, 1914.

To all whom it may concern:

Be it known that I, ANTHONY ammie, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Oil-Seed Cookers, ofwhich the following is a specification, reference being had'to theaccompanying drawings, in which s Figure 1 is a front elevation of mycooker, with a portion of the feeding chute broken away; Fig. 2 is aside elevation with a portion of the casing broken away; Fig. 3 is aplan view; Fig. i is a section on line IV-IV of Fig. 2; Fig. 5 is a planview on an enlarged scale of the controlling mechanism, with the coverof the gear boX removed; Fig. 6 is a section on line VIVI of 5; Fig. 7is a side view of the control mechanism with a portion of the gearboXbroken away and some of the gear wheels removed; Fig. 8 is a detailof the mechanism by. which the over all timing device can be thrown outof operation; Fig. 9 is a detail view partly in section showing themanner in which the over all timing mechanism and the gate operatingmechanism are connected; Fig. 10 is a detail view of the lever devicewhereby the over all timing may be manually controlled; Fig. 11 is adetail view showing the manner in which the over all timing device maybeadjusted; Fig. 12 is a detail view of the timing wheels of the gateoperating mechanism; Fig. 13 is a detail view .of the wheels by whichthe timing of the gate operating mechanism may be adjusted; Fig. 14 is adevelopment of the ratchet wheels of the gate operating mechanism; Fig.15 is an enlarged view of a locking device for the gates, and Fig. 16 isa plan view of this locking device.

My invention relates to cookers for treating seed from which the oil isto be removed by subsequent pressing, such as cotton seed, and dealsparticularly with those cookers in which the seed meal is warmed in onekettle, cooked in one or more other kettles, and then retained and keptwarm in a last kettle, and has to do with the manner in which the mealis passed from one of these chambers to the next. Heretofore suchcookers as have been designed to'operate continuously have been soarranged that the meal was either continuously discharged Specificationof Letters Patent.

from one kettle to the next, or was -discharged in small quantities atfrequent intervals. In the cookers just described it is inevitable thatsome portions of the seed will be passed through a kettle and be dis-.meal from one kettle to another will be mechanically controlled.:Ihis'operation permits the uniform cooking of the meal in each kettleand enables the production of properly cooked meal independent of thereliability or skill of the operator.

'My invention also consists in the construction and operation of thevarious parts which I shall hereinafter describe and claim.

-Referring to the drawings in which I have shown a preferred embodimentof my in vention, the letters A, B,.C and D indicate four superimposedkettles which may be made of cast iron or any other suitable material;and consists of a central chamber 2 construction. used as a receivingchamber in which the meal is warmed. Kettles B and G are cooking kettlesand kettle D is a retaining cham her in which the cooked meal is keptwarm until takento the oil press by the operator.

surrounded by a steam jacket 3 of ordinary Kettle A is intended to beThe kettle A is provided with a lid 4, while the bottom of kettle Aserves as a lid for the kettle B, the bottom of the kettle B as a lidfor the kettle C, and the bottom of the kettle- O as a lid for thekettle D. Connected with the steam jacket of each ofthe kettles A, B, Cand D is'a steam inlet pipe 5, provided with a gage 6 and a reducingvalve 7 andconnected with a common steam supply pipe 8, which may besupplied with steam from any convenient source. By providing a separatereducingvalve 7 for each of the four kettles any desired pressure ofsteam may be maintained in the jacket 3 of each 1 In the'lid e of kettleof the four kettles.

A is an opening 9, to which the ineal or seed tobe cooked is brought bya rotary conveyer 10 from the chute 11. The chute 11 is provided with agate 12, which may be closed to prevent meal being introduced into thekettle A. When the gate 12 is closed the seed meal will pass through theauxiliary chute 11. into any convenient receptacle. The gate 12 isoperated by a lever 13 and a rod 14, which is attached to the arm 15.The arm 15 is keyed on the shaft 16, to which is attached a hinged gate17 in the floor of kettle A. The arm 15 is driven by the rod 18, whichis attached to the controlling mechanism, as will be hereinafterdescribed. The kettle B has agate 19, similar to the gate 17, which isattached to the shaft 20, in which is keyed the arm 21, driven by therod22, which is likewise at tached to the contr lling mechanism. The kettleC has a similar gate, not shown, operated by the arm 23 and the rod 24;,which is likewise attached to the controlling mechanism. Leading fromthe bottom of the kettle D is'a chute 25,which is manually controlled bya slide 26. Through the center of the kettles runs a shaft 27,provided'with stirring paddles 28 in each of the kettles.

The shaft 27 is driven through bevel gears 29 and shaft 30 by anyconvenient source of power applied to the pulley wheel 31.. A

sprocket chain 32 serves to connect the shaft 30 with the rotaryconveyer'10 The shaft 30 likewise carries a pulley 33, which isconnected with pulley. 34 on the controlling mechanism, by the belt 35.Each of the kettles A, B, C and D is provided with a door 36 forcleaning purposes. Y 7

'My preferred form'of controlling mechanism consists of a gear boX 37,provided with bearings 38 and 39, in which the shaft 40 is rotated bythe pulley 34 at a speed of approximately 72 R. P. IVL Throughthe reducing gears 41, shaft 42 and reducing gears 43 the shaft A is drivenata speed of.4 R. P. M. The shaft 44 carries the two crank disks45 and46, having the eccentric pins 47 and 48. Attachedto the eccentric pins47 and 48 are connecting rods 49 and 50.

These connecting'rods l9 and 5O serve to give a'reciprocating motion tothe shaft 51'.

The shaft 51:is carried by the arms 52, which are pivoted to the shaft53. On the shaft 5l are pivoted pawls 54, 55, 56, 57, 58, 59 and 60. Inthe embodiment which is herein described the parts are so proportionedthat these pawls will have a four inch working movement. The: shaft '53has keyed to it a ratchet wheel 61, designed to I cooperate with thepawl 54, a ratchet w'ieel 62. designed to cooperate witlrthepawl 55,

a ratchet wheel 63 designedrto cooperate with the pawl 56, a ratchetwheel 6 de-- I signed to cooperaterwith the/pawl 57, a

ratchet wheel 65 designecl to, cooperate with wheel cooperates with thelever 73, to

which is attached the rod 18. The cam wheel 71 cooperates with the lever7%, to which is attached the rod 22; the cam wheel 72 cooperates withthe lever 75, to which is attached the rod 24. The levers 73, 7% and 75respectively carry w ights 7 6, 77 and 73, which are slidably mounted onthe said rods and maybe held in any desired position by set screws 79.The weights 76, 77 and 78 serve to keep strain on the rods 11, 22 and24: under normal conditions, and thus keep the doors in the floor ofkettles A, ll and C normally closed. [is the cam wheels 70, 71 'and'72rotate, the levers 73, 74 and 75 are raised and open the doors in thefloors of the kettlesA, B and C.

I have found that under ordinar ope"- ating conditions it is desirablethat the gates in the floors of the kettles A, B and 0 should remainclosed for about twenty minutes and that the in the floor of kettleCshould then open and remain open long enough for all of the charge inkettle C to be dumped intothe kettle D;'that as the gate in-the floor ofkettle G closes, the gate 19 in the floor of kettle B should open andremain open long enough for the charge in kettle B to be dumped, andlikewise as the gate 19 closes the gate 17 in the floor of kettle Ashould open and remain open long enough for the charge in the kettle Ato be dumped. Ingeneral practice, these gates will not have to be keptopen more of adjustment, means he provided for contime which each oftrolling the length of remainropen so that the bottom gates "shall thegates will remain open only just long enough to allow the entire batchto be dumped. "The manner in which these results are accomplishedbymycontrol meclr anism is as follows: The'ratchet wheels positioned on theshaft 53 are divided into two groups. The ratchet wheels 61, 62, 63,

64, 65 and 66 keyed to the shaft 53, and through these wheels the actualrotation of the cam wheels 70, 71, and 72, and therefore the actualgate-handling operations, are performed, and also the times during whichthe gates will remain open is controlled. The wheel 67 and the ratchetwheels 68 and 69 which are fastened one to the other, but revolve freelyon the shaft 53 regulate the over all time interval, that is, theinterval between openings of a given gate.

The ratchet wheel 61 is provided with four teeth 61, 61, 61 and 61 whichare positioned at intervals of eight inches on the circumference asshown in Figs. 12 and 14. When one of these teeth is brought under thepawl 54 the wheel 61 is rotated by one stroke through four inches of itscircumference.

The teeth on the wheel 61 are so positioned in relation to the cammingsurfaces ofthe wheels 70, 71 and 72 that when the first tooth 61 on thewheel 61 is moved it ro-- tates the shaft 53 and with it the wheel 72,the camming surface of which raises the lever 75, and through the rod 24the arm 23 opens the gate in the floor of the kettle C, thereby allowingthe charge in the kettle C- to be dumped into kettle D. When the secondtooth 61 of the wheel 61 is driven forward by the pawl 54, the lever 75is allowed to drop, closing the door in the floor of kettle C, andimmediately thereafter the lever 74 is raised by the cam wheel 71, andthe gate 19 opened, allowing the charge in kettle B'to be dumped intokettle C. Then the third tooth 61 on wheel 61 is driven forward by thepawl" '54, the lever 74 drops, closing the gate 19, and immediatelythereafter the cam surface on wheel 70 raises the lever 73 and opens thegate 17, allowing the charge in kettle A. to' be dumped into kettle B.At the same time'the gate 12 is closed (through the arm 13, and the rod14 pivoted to the arm 15) so that at the time the gate 17 is opened, noraw meal can be admitted to kettle A. The fourth tooth 61 on wheel 61serves to close gate 17 and reopen gate 12. v

It is to be understood, however, that as the pawls carried by the shaft51 have only a four-inch movement, and as the teeth on wheel 61 areeight inches apart, there are idle spaces on the circumference of wheel61, between the teeth, over which the pawl 54 will slide smoothlywithout causing the wheel 61 to rotate. As shown in Figs. 12 and 14, theratchet wheel 62 is provided with three sets of teeth 62*, 62 and 62,there being eight one-half inch teeth in each set. These teeth are sopositioned that they come immediately behind the first three teeth ofwheel 61. Above the wheel 62 there is provided a shield 80, whichencircles the shaft 53 and is held in permanent position by the arm 81,which encircles the shaft 42. This shield 80 is so located that the pawlwill be able to engage only one of the onehalf inch teeth on the wheel62 in each stroke. By this arrangement, after the first tooth 61 on thewheel 61 has been driven rapidly forward by the action of pawl 54, thefirst tooth of the first set of teeth 62 on wheel 62 is brought intooperative relation with pawl 55. This pawl driving the wheel 62 aroundat the rate of only one-half an inch of its circumference per strokewill, at the end of eight strokes or two minutes, bring the second tooth61 on wheel 61 into position to be driven forward by pawl 54. hen thefirst set of teeth 62 on wheel 62 is in operative relation with pawl 55,owing to the short movement that is given by each impulse of pawl 55,the

shaft 53 rotates relatively slowly and during this time the broadcamming surface of cam wheel 72 will remain in operative relation withlever 75 and the gate in the floor of kettle C will be kept open. Whenthe second tooth 61 on wheel 61 is driven forward by pawl 54, shaft 53is again given a rapid rotation, so that only the time of one forwardstroke of pawl 54 or one eighth of a minute is consumed-in closing thegate in the floor of kettle C and opening the gate 19 in the floor ofkettle B.

The operation of pawl '54 on the second tooth 61 on wheel 61 will, inturn, bring the second set of teeth 62 on wheel 62 into operativerelation with pawl 55, and the pawl 55 will take eight strokes or twominutes to bring the third tooth 61 on .wheel 61 into operative relationwith the vpawl 54. In like manner the third set of teeth 62 on the wheel62 will bring the fourth tooth 61 on the wheel 61 into operation. Afterthe fourth tooth 61 on the wheel 61 has been driven forward so that allof the gates in the floors of the kettle are closed, smooth portions ofthe wheels 61 and 62 will be under pawls- 54 and 55, so that no rotationof these wheels will be caused by these pawls.

In order that the length of time which each of the gates may be leftopen may be separately adjusted, I provide the ratchet wheels 63, 64 and65, each ofwhich has one tooth 63, 64*, and 65. Above the wheel 63 Iprovide the shield 82, the position of which may be adjusted by the arm83; above the wheel 64 is a shield 84, adjustable by the arm 85, andabove the wheel 65 is a shield 86, adjustable by the arm 87. Therelative position of the teeth 63 64 and 65 on the wheels 63, 64 and 65is shown in Figs. 13 and 14. Fig. 1.3 also shows the manner in which theshields 82, 84 and 86 are adjusted. This adjustment is maintained by theuse of a guide 88 and a pin 89 as is shown in Figs. 5 and 7. The teeth63*, 64 and 65 on wheels 63, 64 and 65 are so located with reference tothe three sets of eight teeth 62, 62 and 62 on wheel 62 that if theadjustable shields 82, 84 and 86 are placed parallel with the shield 80,the tooth 65 on wheel 65' will come into operative relation with. thepawl 56 at the same time that the last tooth in the first set of teeth62 on the wheel 62 comes into operative relation with the, pawl 55, thetooth 64$ on wheel 64 will come into operative relation with pawl 57 atthe same. time that the last tooth in the second set of teeth 62* onwheel 62 comes into operative relation with pawl 55, and the tooth 63 onwheel 63 will come into operative relation with pawl 58 at the same timethat the last tooth in the. third set of teeth62 on wheel 62 comesintooperative relation with pawl 55. As the pawls 56, 57 and 58 drive thewheels 68, 6 1- and 65 forward only onehalf an inch withthe shields 82,Si and S6 in this position, none of the wheels 63, 64 or 65 have effecton the rotation of the shaft 53, and the full two minutes of opening isallowed for each of the gates in the bottoms of kettles A, B and C. If,however, the shield '86 is set back a space of one-half an inch, pawl 58picks up teeth 65 on wheel 65 at the same time that pawl engages the sventh tooth of the firstset of teeth 62 on wheel 62, and wheel is drivenforward one inch, that is, two tootlrspaces, carrying with it shaft 53,soith'at'the rtime tha t the door in the floor of kettle '0 remains openis shortened by one-quarter of a minute. For every one-half an inch thatshield 86 is: set back, one tooth in the first set of teeth 62 ,011 thewheel 62 is thrown-out of operation, and the length of time for whichthe gate in the floor of kettle remains open, is shortened a. quarter ofa minute. Thus, by the ad ustment of shield '86, the time which the gatein the floor of kettle 0 remains open may be adjusted at quarterminute.intervals, from one-quarter of a minute to two minutes. i in exactly thesame manner Lh length of time which the gate 19 7 in the floor of kettleB remains open may be ad'usted bv shiftin the shield 8 1 and the lengthof time which the gate 17 in the 1 floor of kettle A. remains open maybe adusted by shifting the position of shield 82.

As has already been stated, when the fourth tooth 61 on the wheel 61 hasbeen driven forward by the pawl "t, the pawls 5 1 55,

56, 57 and 5S contactwith smooth portions of their respective wheels,

and cause no I fnrtherrotation of shaft -After the gate l'lllnS beenclosed,'the gate-opening mechanism remains at rest until the meal hasbeen cooked for a sufficient length of time, and then againis broughtthe l over all timing apparatus, consists in wheels. 67 ,68 and 69.These wheels rotate together. The ratchet wheel 68 is provided withninety-two one-half inch teeth. The, pawl 59 which engages the wheel 68has a snflicient movement, owing to the reciprocation of shaft 51 tooperate eight teeth per stroke, but a shield 90, is provided whichprevents pawl 59 from moving the wheel 68 more than one tooth perstroke. The ratchet wheel 69 which is attached to ratchet wheel 68, hasonly four teeth, and these teeth are separated by a distance at least asgreat as eight of the teeth on ratchet wheel 68. The relative positionsof ratchet wheels 68 and 69 is shown in Fig. 11. ,An adjustable shield91 is provided to control the engagement of pawl 60 with the'teeth ofratchet wheel 69. lVith this shield 91 placed exactly parallel to theshield 90, it will take ninety-two strokes of thepawls 59 and 60 torevolve the wheels 68 and 69, and as the pawls move four timesinaminute, this will take twentytl ee minutes. If, however, the shield 91be r volvcd backward to the position shown in 11, it will uncover theteeth on wheel 69 one tooth-space in advance and the pawl 60 will, whenatooth comes around, catch it in time to move wheel 69 and with it wheel68 two tooth-spaces in one stroke. This action occurs with each of thefour teeth on wheel 69, and consequently shortens 'up the period ofrevolution of these two of revolution of wheels 68 and 69 can bereg-=nlated to take up from SlXiZeGIl to twentythree minutes. Theadjustment. of shield 91 is accomplished by means of the lever 92,

whiohmay be held in proper position by a pin as 89 inserted in the guide'88.

The "connection between the over-all timing apparatus and thegate-operating mechanism, consists in lug 93 on the wheel 66, which iskeyed tothe shaft'53, as is shown inFigs; 9 and 10, and in the lug 9 onwheel 6?, which is attached to wheels 68 and 69.. These two lugs 93-and'9-l c06perate as follows lVhen the first tooth on wheel 61 isdriven forward by pawl 54:,

wheel 66 will movemore rapidly than wheel 67 andlng will stay ahead oflug 91 until the fourth tooth on wheel 61 has been driven forward bypawl. 5%. Wheel 66, together with shaft 53 and the other wheels whichare keyed to this shaft, will then remain at rest until the Wheel 67 isrotated so that lug 94 catches up with and engages'lug 93. Then aswheels 68 and 69 rotate they will carry with them the various wheelskeyed to shaft 53, until the first tooth on wheel 61.

is again brought into operative relation with pawl 54, whereupon wheel66 will once more rotate more rapidly than wheel 67 and lug 93 willremain ahead of lug 94 until the gate-opening operation is completed. Bythis arrangement the adjustment of the time that the gates remain openis made entirely separate from the over all adjustment during which allof the gates remain closed.

If desired, the ?over all timing of the oil seed cooker may be madedirectly dependent upon the control of the, operator, instead of havingthe operation mechanically governed. I have provided in my device meanswhereby the over all timing mechanism may be disconnected, and meanswhereby the operator can manually set the gate-opening mechanism intooperation. To accomplish this result a shield-lever 95 is positionedcontiguous to the wheel 68 as is shown in Fig. 5. The shield-lever 95 isprovided with a slot 96 through which passes a screw 97 by means ofwhich the lever 95 is attached to the bracket 98, which is an integralpart of the casing 37. As shown in Fig. 8, the lever 95 has a shoulder99 on its upper edge and a recess 100 in its lower edge. The lever 95 islikewise provided with a vertical slot 101 and a circular hole 102.WVhen it is desired that the over all timing mechanism shall be thrownout of operation the lever 95 is moved into the position shown in Fig. 8and a pin, as 89, is passed through the slot 101 into the guide 88. Inthis position the shoulder 99 is immediately below the point where thepawl 59 will normally engage the teeth of the wheel 68. On the face ofthe wheel 68 is provided a pin 103, which is so located that just beforethe first tooth on wheel 61 is brought into engagement with the pawl 54,this pin engages and lifts the lever-arm 95, so that the shoulder 99will prevent the awl 59 fro-m engaging the teeth of the wheel 68. Whenit is desired to use the over all timing mechanism, the lever 95 ispushed into the casing as far as allowed by the slot 96 and the pin, as89, is passed through the hole 102, instead of the slot 101, into theguide 88. When the lever 95 is in this position it is inoperativebecause the rotation of the wheel 68 causes the pin 103 to enter therecess 100 in the lever 95 instead of striking the lever and lifting it.I

To set the gate-opening mechanism into operation when the over alltiming device is disconnected, I supply a ring 104, which rotates aboutthe inwardly projecting portions 105 and 106 of the wheels 66 and 67respectively, as is shown in Fig. 9. Extending from the ring 104 is alever 107, and also a projection 108, to which are pivoted pawls 109 and110, adapted to cooperate with the teeth on wheels 66 and 67respectively.

When the lever 95 has been set so the mechanism operates without theover all timing device, the wheels all rotate in their usual manneruntil, just before the time when the first tooth 61' on wheel 61 isbrought into position to co'ciperate with pawl 54. The pin 103 on thewheel 68 then raises the lever 95, which engages the projecting edge ofthe pawl 59 and holds it out of operation, and the mechanism isthereupon brought to rest. To start the mechanism again the lever 107 ismanually raised, until the pawls 109 and 110 engage teeth on the wheels66 and 67, and is then lowered, thereby rotating the wheels 66 and 67and through them, all of the ratchet wheels of the device. As therotation of the wheel 68 is thus continued it causes the pin 103 to movealong the under side of the lever 95 and enter the recess 100. This willallow the lever 95 to drop, and thereupon pawl 59 will be able to engagewheel 68 in its usual manner, and the automatic operation of themechanism will be resumed.

The lever 107 can likewise be used to bring the various wheels into anydesired position when the machine is at rest. For

example, when the machine is first started up, it will be desired tobring the mechanism into the position where the gate 17 has just beenallowed to close. This can be readily done by manual actuation of thelever 107.

The weights 76, 77 and 78 are ordinarily sufficient to hold the gates inthe floors of the various kettles closed, but in order to insure againstaccidental opening I provide a lock for each of the gates. My preferredform of lock is shown in detail in Figs. 15 and 16, as applied to gate19. Referring to these figures, the gate shaft 20 has keyed on it, nearits outer end, a sleeve 111, having a segmental recess 112, which formsshoulders 113 and 114. Integral with the sleeve 111 is a cam wheel 115having a shoulder 116. The arm 21 is provided with asleeve 117, whichpivots on the shaft 20 and has a segmental projection 118, with faces119 and 120. The segmental projection 118 fits into and is adapted toco-act with the segmental recess 112. Pivoted above the cam wheel 115 isa stop lever 121, provided with a shoulder 122. Pivoted to the stoplever 121 is an arm 123, provided with a slot 124. A bolt 125 passesthrough the rod 22, the slot 124 of the arm 123 and the arm 21. When thegate 19 is closed, the parts are in the position shown in Fig. 15. Asthe rod 22 is raised, the arm 123 raises the stop lever 121, so that theshoulder 122 becomes disengaged from the shoulder 116. The face on thesegmental projection 118 then engages the shoulder 114 on the segmentalre cess 112, and further upward movement of the rod 22 will cause thegate 19 to open. After the gate 19 has remained open a sufficient lengthof time, the rod 22 drops causing the sleeve 117 to rotate, and by theengagement of the face 119 of the segmental projection 118 with theshoulder 113 of the segmental recess 112, the gate 19 is closed. At thesame time the shoulder 122 is allowed to ride up the cam surface of thecam wheel 115, owing to the playof the bolt 125 in the slot 124. Whenthe gate 19 is completely closed the shoulder 122 drops by gravitybehind the shoulder 116, and the gate will be locked.

In order to prevent undesirable rotation of the wheels 67, 68 and 69 Iprovide a look ing pawl 126 pivoted on the shaft 4-2 adapted to engagethe'teeth on ratchet wheel 68.

It is obvious that any desired number or arrangement of kettles may beemployed, or any suitable form of controlling mechanism may be utilizedto accomplish the results attained by my invention, and that variousother modifications may be made in the structure which I have shown anddescribed herein without departing from my invention.
